Multiparameter noninvasive sepsis monitor

Abstract

A system for monitoring sepsis comprises one or more sensors that noninvasively monitor a patient to produce sensor data and processing circuitry to: derive, from the sensor data, one or more physiological parameters of the patient that are indicative of a sepsis state of the patient; apply a set of rules to the one or more physiological parameters; determine a sepsis state for the patient based on the set of rules applied to the one or more physiological parameters; and output at least one signal indicative of the sepsis state of the patient. The system includes an output device that outputs a notification based on the at least one signal.

What is claimed is: 
     
         1 . A system for monitoring sepsis, comprising:
 one or more sensors that noninvasively monitor a patient to produce sensor data;   processing circuitry to:
 derive, from the sensor data, one or more physiological parameters of the patient that are indicative of a sepsis state of the patient; 
 apply a set of rules to the one or more physiological parameters; 
 determine a sepsis state for the patient based on the set of rules applied to the one or more physiological parameters; and 
 output at least one signal indicative of the sepsis state of the patient; and 
   an output device that outputs a notification based on the at least one signal.   
     
     
         2 . A device for monitoring sepsis, comprising:
 processing circuitry to:
 derive, from sensor data of one or more noninvasive sensors, one or more physiological parameters of a patient that are indicative of a sepsis state of the patient; 
 apply a set of rules to the one or more physiological parameters; 
 determine a sepsis state for the patient based on the set of rules applied to the one or more physiological parameters; and 
 output at least one signal indicative of the sepsis state of the patient.
